Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coordination compound or unspecified salt
Note (C)(3) directs coordination compounds to last appropriate heading; 2942 residual.
If prepared with anti-dusting agent for specific industrial use
Note (g) limits additives; excess renders 'particularly suitable' for specific use, moves to mixtures.
If polymerized form
Polymerized amides classify under Chapter 39 plastics, not monomeric Chapter 29 compounds.

Import Tips & Compliance
• Specify organic base vs inorganic acid in salt formation per note (C)(2) for classification
• Anti-caking agents allowed only if necessary for transport per note (f); excess triggers reclass
• Industrial vs pharma end-use affects marking; misdeclaration common pitfall
